With the "Apple Silicon" announcement earlier this year, are there any plans for macOS/arm64 support? As I understand it this at least requires updates to the avr-toolchain and avrdude along with other stuff I may not be aware of.

My primary interest is in getting avrdude working on an arm64 Mac. I've got access to one of the dev kit machines and have managed to compile a version on it. However, I've yet to successfully flash an Arduino from with the same parameters I've used from an Intel Mac.

I realize that some of the above may be better suited to the arduino/avrdude-build-script repo (which I just discovered), but I'm also generally interested in the Arduino IDE on this upcoming platform.
